SPRING MOUNTING FOB CUSHION CONNECTIONS.

Application filed October 25, 1922. Serial No. 596,737.

To all whom it may concern:

Be it known that we, ALFRED F. Mason and AUGUST H. Lnirnn'r, citizens of the United States, residing, respectively, in the borough of -Manhattan and'in the borough of Queens of the city of New York, inthe- State of New York, have invented. certain new and useful Improvements in Spring Mountings for Cushion Connections, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

This inyention relates to the type of con nection disclosed by Letters Patent of the United States No. 1,400,563 dated December 20, 1921, and No. 1,404,876 dated January 31, 1922. In such a connection it is proposed to connect one or both ends of a vehicle spring to the frame through a nonmetallie yielding block maintained against displacement with respect to the frame and the spring end. In the preferred embodiment it was proposed to provide seats on the spring ends for the non-metallic block and secure the block onto the end under compression. Ordinarily, two leaves of each sprin were of; substantially the same length an the block or blocks were seated on the remote faces of these leaves. When pressure was applied to confine the material of the block or blocks under compression the leaves were forced together thereby setting up a degree of friction against relative movement between the leaves as during elongation of the spring. This condition might prove objectionable under some circumstances and the present invention seeks to eliminate it by providing seats for the block or blocks carried with the sprin end and maintaining the material of the bi bck against displacement with respect to the spring end and permitting its confinement under pressure without, however, setting 'up pressure between proximate spring leaves and so opposing relative sliding movement therebetween. In accordance with the invention it is proposed to make the proximate spring leaves of different lengths and form one of the seats independent of one of the leaves. More particularly, in the preferred embodiment it is proposed to provide a seat on the to most leaf and secure a spacer block to tl ie remote side of said leaf which spacer may be of greater thickness than the proximate spring leaf and carry a seat for the material of the block. and relieve the last named spring leaf of the compression pressure a plied to the non-metallic material when t e parts are assembled. The invention will be described with greater particularity in connection with the illustrated embodiment in the drawings wherein:

Figure l is a view partly in side elevation and partly in vertical section showing suitable cushion connections between the ends of a rear springvand the frame.

Figure 2 is a fragmentary view partly in side elevation and partly 1n section of a suitable cushion connection between the rear end of av front spring and the frame.

It will be evident as the description proceeds that the invention is not to be limited to the particular form of any of the elements employed nor to the material or number of parts. In the drawings there has been shown so much of a motor frame and its spring as is necessary for an understanding of the application thereto of an embodiment of the improvements which will illustrate the principle. The frame a may have secured thereto housings b, 0, open at b, a, on their proximate ends to receive the ends of a vehicle spring d, respectively, the embodiment of Figure 1 showing a rearspring and the embodiment of Figure 2 showing a front spring. In accordance with the broad invention described by the. patents hereinafter referred to, it is proposed to connect the ends of the spring cl with the frame a through non-metallic yielding material. This may be done in one construction by introducing the ends of the spring into blocks 0, c,'of rubber or other suitable material and confining these blocks within the housings b, c, by caps b held in place by bolts b, 0 respectively. In some embodiments instead of employing a single slotted block such as e or 6 separate blocks of material above and below the spring leaves may be employed. The invention is not to be limfor the non-metallidmaterral on an element ited as to the particular type of non-metallic connection employed. In accordance with the invention one of the spring leaves d is made of such length as to extend into the material of the blocks a, e, and the roximate leaf d v is made shorter than the.

rst named leaf. The leaf, (1 may be formed with or carry seated, d, at its opposite ends for the material of the blocks e, 6', respectively, to hold said material.

against displacement with'respect to said leaf. Under some conditions it is desirable that the two leaves d'g-d, may slide freelyon one another during elongation of the spring. Since the material of the blocks 6, e, is confined under compression it is evident that if the leaf d was afforded a .seat for. the material such friction would of the leaf d". These blocks are preferably of greater thickness than the leaf 0? and in all positions of the spring are spaced from the ends of said leaf. It is proposed to form the spacer blocks f, f', with or secure thereto seats 9, g, respectively, for the material of the blocks 6, e, such seats being of such character as to supplement thev first named seats (1 d, and assist in holding the material of the non-metallic connection against. displacement with respect to the spring. A simple means of assembling the parts and securing them in fixed relation has been illustrated asrivets 2', i, which may use through the seats d d, the spring eaf d, the spacer blocks f, f, and the spring seats g, g', respectively. .By making the spacer blocks f,f, thicker than the spring leaf d the seats, whether formed with spacer blocks or carried therewith (as illustrated) will hold the non-metallic material'of the blocks 6, 6', outof engagement .with thesaid leaf so that the latter may move freely-with respect to said material and such movement with respect to the spring leafd' will not'be opposed by the confining pressure on the material.

It is evident that the blocks e, 0', instead of being formed integrally may be divided into parts seated properly within the respective housings on the spring ends and that the means for maintaining the said blocks in engagement with the spring ends and with the frame may be changed without departing from the present improvements.

In Figure 2 corresponding arts are indicated byv corresponding re erence characters in capital letters.

What we claim is: K

1. In a cushion connection of the character described in combination with a leaf spring and non-metallic material to be confined on the end thereof under compression, a leaf on-which the material'isseated and a spacer element secured to said leaf and having said material-seated on its remote face.

2. In a cushion connection of the character described in combination with a leaf spring on the end of which is confined under compression a non-metallicmaterial, a leaf on which said material is seated, a proximatejleaf shorter than said first'named leaf and a spacer block secured to said first named leaf to afford a seat for the material on its remote face and relieve the second named leaf of the compression pressure 1mposed on said material.

3. In combination with the frame and leaf spring ;of a motor vehicle a housing secured to the frame and having an open end into which the. end of the spring extends, non-metallic material confined within said housing under compression, one of the leaves of said spring extending into said material and carrying a seaton which the material rests, the .proximate spring leaf being shorter in. length, a spacer block of greater thickness than the last-named leaf secured to the first named leaf in line with the second named leaf and affording a seat for said material and relievin the second named leaf of the compression pressure thereon. a

4; In a cushion connection of the character described in combination with a leaf spring and non-metallic material to be confined on the end thereof under compression, means to relieve the ad'acent leaves of the spring of friction there etween induced by said compression pressure.
